Why Choose Dual Wavelength Laser (980 nm + 1470 nm) for Varicose Veins (EVLT)?

The V6 endovenous laser system offers two clinically proven wavelengths—980 nm and 1470 nm—each with distinct advantages for treating varicose veins. Combining both wavelengths provides optimal clinical outcomes in Endovenous Laser Treatment (EVLT).

980 nm Laser:

This wavelength exhibits balanced absorption in both water and hemoglobin, making it a powerful, versatile tool for endovenous ablation. With an output power of up to 30 watts, it delivers strong, reliable energy for effective vein closure, especially in larger-diameter veins.

1470 nm Laser:

This wavelength has significantly higher absorption in water, resulting in more precise energy delivery and reduced thermal spread to surrounding tissues. This minimizes collateral damage and enhances patient comfort, making it ideal for delicate anatomical areas.

Clinical Recommendation:

For optimal results, a dual-wavelength approach (980 nm + 1470 nm) is highly recommended. The combination leverages the high power of 980 nm and the precision of 1470 nm, ensuring effective vein closure with minimal side effects and improved postoperative recovery.

The EVLT Procedure: Step by Step

Endovenous Laser Therapy (EVLT) is a minimally invasive procedure that uses laser energy to close malfunctioning varicose veins. The laser fiber is inserted directly into the affected vein—hence "endovenous," meaning within the vein. Here is the standard procedure:

Local Anesthesia:

A local anesthetic is administered at the treatment site, and a small needle is inserted into the target vein.

Guide Wire Insertion:

A thin guide wire is passed through the needle and advanced into the saphenous vein under ultrasound guidance.

Catheter Placement:

The needle is removed, and a catheter (a thin plastic tube) is threaded over the wire and positioned within the vein.

Laser Fiber Insertion:

A radial-emitting laser fiber is inserted through the catheter and advanced until its tip reaches the proximal (highest) point of the diseased segment—typically near the groin crease.

Tumescent Anesthesia:

A solution of local anesthetic is injected around the vein using multiple small needle entries or continuous infusion. This compresses the vein, protects surrounding tissues, and reduces pain during laser activation.

Laser Activation and Fiber Withdrawal:

The laser is activated, and the fiber is slowly withdrawn 1 cm at a time, delivering controlled thermal energy along the vein wall over 20–30 minutes.

Vein Closure:

The heat causes uniform contraction and permanent occlusion of the vein wall, sealing the vein shut. Blood is naturally rerouted to healthy surrounding veins, restoring efficient circulation and eliminating symptoms such as swelling and discomfort.

Completion of Procedure:

Once treatment is complete, the laser fiber and catheter are removed. The entry site is covered with a small dressing.

Post-Treatment Notes:

The entire procedure takes approximately 20 to 30 minutes per leg. For optimal cosmetic and functional results, smaller collateral varicosities may require additional sclerotherapy either during or after EVLT.
